The precise origin of the spurious data is unclear, and "informed" sources have pointed to a number of possible causes. The root cause is extraneous "ghost" directory information on some hard disks that Apple has been shipping in newer Macintosh models. The problem, although potentially serious, is easy to detect and, if you've already been hit, you may be able to recover your data.ĭefining the Problem - There are actually two problems: the first resides on the hard disks themselves, and the second lies with the way NDD reacts to those hard disks. If a user tells NDD to fix these problems, the program may crash toward the end of the repair, rendering the disk unable to boot and apparently losing all data. Symptoms include NDD reporting errors with disk directory information and allocation block sizes. Sounds OK but now that copy will not start-up fully, flashing floppy icon and must force quit.Last week, problem reports began circulating about troubles with Norton Disk Doctor (NDD) and newer Macintosh models, particularly new Power Macs. dev/rdisk4s2: ** The volume MacOS9 was repaired successfully. dev/rdisk4s2: ** Checking volume information. dev/rdisk4s2: ** Checking volume bitmap. dev/rdisk4s2: ** Checking catalog hierarchy. dev/rdisk4s2: ** Checking multi-linked files. dev/rdisk4s2: ** Checking extents overflow file.
dev/rdisk4s2: ** Checking non-journaled HFS Plus Volume. Not much else going on so run up ElCap's Disk Utility, see the container drive, see the active MacOS9 volume within it and so run Repair/Check on that: dev/rdisk4s2: Executing fsck_hfs (version hfs-305.10.1). dev/rdisk4s2: /dev/rdisk4s2: ** /dev/rdisk4s2 (NO WRITE) Hdiutil attach -nomount -noverify -noautofsck (FIRST MAKING SURE SS/MACOS 9 WAS CORRECTLY EXITED) Applications/MacOS9/Mac\ OS\ 9.app/Contents/Resources/Files/MacOS.sheepvm/MacOS9.sparsebundle I had been moving a fair bit of files around in the OS9 virtual system drive, and it seemed a good idea to look at empty trash and maybe "hdiutil compact" the host sparse image at Well I started in host MacOS 10.11 since this is where I want to copy and preserve my data and figure I have the latest tools especially if I end up need AFPS etc in the mix (where i am also making moves towards moving to Mojave if I can assure myself on a few points first.)
Working on backups I tried various things to investigate and maybe fix.įirst major choice was to do it from within OS9 using a number of Apple or 3rd party tools I have used over the centuries (starting in 19xx). I was looking into the sparse bundle and backups of my MacOS9 configuration and noticed there seemed to be some errors, maybe, in the bundle.
I have been using Edwards ready built 64bit SS based MacOS9 and moved my databases in there from ChubbyBunny where they had been for some years. I realise I am unclear about the best way to check for and fix any disk errors that might be found in the SS emulated world.
